Butler, Martinez 'fight over nether regions'

Gerard Butler and Olivier Martinez have reportedly clashed over the sizes of their manhood.

The Daily Mirror claims that while on a night out with Paris-born Martinez and his partner Halle Berry at LA's Chateau Marmont, proud Scot Butler began jesting about "effeminate Frenchmen" and their failings in the trouser department.

A source explained: "Halle, Gerard and Olivier were all having a nice conversation at a table when things suddenly took a turn for the worse.

"Gerard began mucking around, bragging about Scotsmen and the size of their packages. He was joking that he could wear kilts and no undies because he was a ‘real man’, and that other Europeans wouldn’t be able to pull a kilt off.

"As the conversation continued, he got more lewd - and funny - but Olivier got less and less impressed. After one gag too many at his expense, he stood up and confronted Gerry. Olivier was red in the face and gesticulating wildly. So Halle told them both to lighten up."

Martinez was accused in December of threatening to attack a photographer outside a Hollywood restaurant.
